Everyone in the managed services industry celebrates hitting $1M ARR. Nobody talks about what happens right after.
You scale from 15 clients to 40. Revenue climbs. The founder gets excited. Then EBITDA quietly collapses — from 28% down to 11% — and nobody can explain why.
Here's what actually happened. At 15 clients, you were the system. You knew every account. Every escalation ran through you. Every renewal was a conversation you had personally. It worked because you made it work. At 40 clients, that same model is a liability. The founder is now the bottleneck on delivery, on renewals, and on new business simultaneously. Margins erode not because the business grew — but because the infrastructure never did.
This is the EBITDA cliff. It's not a revenue problem. It's a systems problem.
The MSSPs that scale past it build two things before they need them: a sales infrastructure that doesn't depend on the founder's relationships, and a delivery model that doesn't break when headcount doubles.
Most wait until the cliff is already happening. By then, the fix costs three times as much and takes twice as long.
Build the infrastructure before the revenue forces you to.
